A marathon runner ran for six hours. Select all the measurements that are equal to six hours.

• 21,000 seconds

• 21,600 seconds

• 10,300 seconds

• 300 minutes

• 360 minutes

Answer explanation

To find the correct answers, you need to change 6 hours into measurements of minutes or seconds to match the answer choices.
There are 60 minutes in an hour so to convert hours to minutes you must multiply by 60.
6 hours × 60 = 360 minutes

There are also 60 seconds in a minute so to convert minutes to seconds you must multiply by 60 again.
360 minutes × 60 = 21600 seconds

Therefore, the correct answers are (360 minutes) and (21,600 seconds).
